Question

The commen difference of an Ap whose general term is an =2n+1 is

Answer 1

Hey there , your answer is 2.

Step-by-step explanation:

General term:

an = 2n+1

a1

a1=2(1)+1

=2+1

=3

a2

a2=2(2)+1

=4+1

=5

Common difference (d) = a2-a1

=(5)-(3)

=2

Common difference = 2

Hope you got this !

Answer 2

Answer:

Question:-

• The common difference of an Ap whose general term is an =2n+1 is

Answer:-

• common difference = 2✔

Explanation:-

• General formula = 2n+1
• Therefore first term=2×1+1=3

Second term=2×2+1=5

Common difference = 5-3=2✔

OR

• We know the formula to find the general term is "dn+(f-d)"

Here d=common difference,

n=nth term,f=first term

• Therefore common difference = 2✔

Hope it helps you better☺
